| Summary: | <h2>Fin whale ear bones: natural mode animation</h2><p dir="ltr">The natural modes of the fin whale ear bones are visualized below. High-amplitude motion is encoded as opaque (red), and low-amplitude motion is transparent. The anatomy representation includes the ossicular chain, and in particular the stapes motion is visible.</p><p dir="ltr">Two opaque stills are also included to show the overall geometry. At the top of the picture is the periotic bone, which is firmly embedded in the skull.</p><h2>Material properties</h2><p dir="ltr">Young's modulus:</p><p dir="ltr">Flexible bone 10 GPa.</p><p dir="ltr">Stiff bone 20 GPa.</p><p dir="ltr">Ligaments 10 MPa.</p><p dir="ltr">Mass density:</p><p dir="ltr">Bones 2500 kg/m**3.</p><p dir="ltr">Ligaments 1200 kg/m**3.</p> |
